Allen-Bradley 20G1AJC750JN4NNNNN PowerFlex 755 AC Drive

1. Product Overview

The Allen-Bradley 20G1AJC750JN4NNNNN is a high-power, air-cooled AC variable frequency drive from the PowerFlex 755 series.

It is designed for demanding industrial motor-control applications where high output current, substantial motor power, reliable speed regulation, integrated industrial networking, and robust enclosure protection are required.

This particular configuration is rated for 400 VAC, three-phase input and provides a nominal output current of 750 A. Its published power ratings are 450 kW for Light Duty, 400 kW for Normal Duty, and 315 kW for Heavy Duty. It uses a Frame 8 construction and is supplied in an 800 mm deep MCC-style enclosure with Type 12 / IP54 protection. 

The drive is air cooled and uses forced-air thermal management, making it suitable for large industrial installations where considerable heat must be dissipated during continuous motor operation.

The model includes embedded EtherNet/IP, making it suitable for integration into industrial automation architectures where the drive needs to exchange commands, status information, operating parameters, diagnostics, and process data with a control system.

Another important characteristic is the Enhanced LCD Full Numeric HIM configuration. Unlike a blank-drive configuration without an operator interface, the JN4 version incorporates an enhanced LCD full-numeric human interface module with an IP66 / NEMA Type 4X/12 enclosure rating. This makes local commissioning, parameter adjustment, troubleshooting, and operational monitoring substantially more convenient. 

The catalog configuration also specifies a filtered drive with the common-mode jumper installed, an AC input with precharge and no DC terminals, and no internal dynamic-braking option. 

4. Electrical Characteristics

4.1 Input Voltage

The 20G1AJC750JN4NNNNN is designed around a 400 VAC three-phase input system.

This makes it particularly suitable for industrial electrical systems commonly used in large manufacturing plants, process facilities, pumping stations, heavy material-handling systems, and other medium-to-large motor installations.

The three-phase input architecture is appropriate for high-power motors because it distributes electrical loading across the three phases and provides the operating structure expected by large industrial AC drives.

4.2 Output Current

The nominal output current is 750 A.

A 750 A output rating places this drive firmly in the high-power industrial-drive category. Such a current capacity allows the unit to control substantially sized AC motors without requiring the application to be divided into multiple smaller drives solely because of drive-current limitations.

The high current rating is particularly useful in applications where motor starting, acceleration, continuous torque production, or process loading can create significant electrical demand.

4.3 Power Ratings

The drive provides three principal application-oriented power ratings:

Duty Classification	Power Rating
Light Duty	450 kW
Normal Duty	400 kW
Heavy Duty	315 kW

These ratings are important because the correct drive should not be selected solely by looking at the motor’s nominal kW value.

Different applications impose different thermal and overload requirements.

A motor driving a relatively smooth centrifugal pump may have a different duty requirement from a conveyor, crusher, mixer, extruder, hoist, or other machine that experiences frequent acceleration and higher torque demand.

For this reason, the 315 kW Heavy-Duty rating is particularly relevant when evaluating applications involving more demanding load conditions, while the 400 kW Normal-Duty rating provides a substantial capacity for conventional industrial motor applications.

5. Mechanical Construction

The 20G1AJC750JN4NNNNN uses a Frame 8 architecture.

Frame 8 indicates that this is a physically large high-power drive rather than a compact wall-mounted inverter intended for small motors.

The catalog description identifies the unit as an 800 mm deep MCC-style packaged drive with Type 12 / IP54 protection. 

This type of construction is especially useful in large industrial installations where the drive is incorporated into a motor-control-center-style electrical arrangement rather than mounted as a small standalone panel component.

5.1 Approximate Dimensions

For preliminary engineering and equipment-room planning, the physical envelope can be considered approximately:

Width: ~600 mm class

Height: ~2,000–2,200 mm

Depth: ~800 mm

Approximate weight: ~500–700 kg

These figures should be treated as engineering planning estimates only.

Because high-power packaged drives can include enclosure sections, power components, cooling equipment, operator-interface assemblies, wiring, terminals, and other configured components, the actual shipping and installed dimensions can vary with the exact configuration.

For final installation design, lifting equipment selection, transportation planning, floor loading, cabinet clearance, and foundation design, the exact dimensional drawing should be used.

6. Operator Interface

One of the distinguishing features of the JN4 configuration is its Enhanced LCD Full Numeric HIM.

The HIM provides a local operator interface for interacting with the drive.

This can be useful during commissioning and maintenance because technicians can access drive information directly at the equipment rather than relying exclusively on a remote control system.

Typical local-drive activities can include:

• Viewing drive operating status.
• Reviewing parameter values.
• Adjusting configuration parameters.
• Checking operating conditions.
• Monitoring faults and alarms.
• Performing commissioning procedures.
• Verifying motor-control settings.
• Supporting maintenance and troubleshooting.

The operator interface is specified with IP66 / NEMA Type 4X/12 protection, giving it substantially more environmental protection than a basic indoor control interface. 

7. Embedded EtherNet/IP

The integrated EtherNet/IP capability is another important characteristic of this configuration.

In a modern industrial automation system, a large motor drive is rarely an isolated device.

The drive normally needs to exchange information with PLCs, HMIs, supervisory systems, production-control systems, and other automation equipment.

Embedded EtherNet/IP provides a convenient communications architecture for these requirements.

Depending on the control architecture and configuration, the drive can participate in functions such as:

• Start and stop commands.
• Speed references.
• Drive status monitoring.
• Fault and alarm information.
• Current and voltage monitoring.
• Frequency and speed monitoring.
• Parameter access.
• Diagnostic information.
• Process-related control information.
• Integration with plant-level automation.

For large installations containing multiple drives, Ethernet-based communications can significantly simplify the control architecture compared with extensive hardwired point-to-point control.

8. Filtering and Common-Mode Configuration

The 20G1AJC750JN4NNNNN is specified as Filtered and with the CM jumper installed. 

The filtering configuration is important in industrial electrical environments where electromagnetic compatibility and conducted electrical noise need to be considered.

Variable frequency drives use high-frequency switching to control motor voltage and current.

That switching behavior is fundamental to modern AC-drive operation, but it can also produce electrical noise that needs to be managed through appropriate drive configuration, grounding, cabling, filtering, and installation practices.

The configured filtering and common-mode arrangement therefore form part of the overall electrical design of the drive system.

9. Dynamic Braking

This particular catalog configuration is specified with no dynamic braking. 

This is an important selection characteristic.

Applications with high-inertia loads, frequent deceleration, rapid stopping, or regenerative energy requirements may need a braking strategy that is different from a conventional free-running or controlled-deceleration application.

For applications involving heavy rotating masses, the engineering team should evaluate:

• Motor inertia.
• Load inertia.
• Required acceleration time.
• Required deceleration time.
• Stop frequency.
• Regenerative energy.
• Mechanical braking requirements.
• Emergency-stop requirements.
• Drive braking architecture.

The absence of an internal dynamic-braking configuration should therefore be considered during application engineering rather than treated simply as an accessory detail.

10. Product Introduction

The Allen-Bradley 20G1AJC750JN4NNNNN is best viewed as a high-capacity industrial motor-control platform rather than simply a conventional compact frequency converter.

Its combination of 750 A output current, 400 kW Normal-Duty capability, Frame 8 construction, IP54/Type 12 protection, embedded EtherNet/IP, forced-air cooling, filtered configuration, and enhanced local operator interface makes it suitable for large and demanding motor-driven systems. 

The design is particularly attractive when the project requires the drive to become part of a larger automation system.

Instead of treating the VFD as an independent motor-control box, the PowerFlex 755 architecture allows it to function as an integrated component of the plant’s control, monitoring, communications, and maintenance structure.

11. Major Applications

11.1 Large Water Pumps

Large water-pumping systems are one of the natural applications for a drive of this capacity.

The drive can regulate motor speed so that the pump operates closer to the actual process requirement rather than operating continuously at full speed.

Potential benefits include improved process control, reduced mechanical stress during starting, and better adaptation to changing flow requirements.

Typical applications include:

• Raw-water pumps.
• Water-transfer pumps.
• Industrial process-water pumps.
• Cooling-water pumps.

• Processing equipment.
• Bulk-material transfer systems.

In conveyor applications, drive control can help manage acceleration and deceleration and reduce mechanical shock compared with uncontrolled motor starting.

11.5 Cement and Building-Material Plants

Large cement and aggregate facilities contain numerous high-power rotating machines.

Possible applications include:

• Large process fans.
• Conveyors.
• Crushers.
• Material-handling equipment.
• Process pumps.
• Dust-collection systems.
• Grinding-related auxiliary equipment.

11.6 Chemical and Process Industries

Large process plants frequently use variable-speed motors for pumps, fans, compressors, mixers, and other equipment.

The combination of local operator control and network communications makes the 20G1AJC750JN4NNNNN suitable for installations where centralized process control and local maintenance access are both important.

• Chilled-water pumps.
• Condenser-water pumps.
• Cooling towers.
• Large supply-air fans.
• Exhaust fans.
• Process ventilation.

The ability to regulate motor speed allows the equipment to respond to changing thermal and airflow requirements.

11.8 Manufacturing Plants

The drive can also be considered for high-power rotating equipment used in:

• Steel processing.
• Metal production.
• Paper manufacturing.
• General manufacturing.
• Material handling.
• Process machinery.
• Large machine auxiliaries.
• Industrial utilities.

12. Main Advantages

12.1 High Output Capacity

The 750 A output rating is one of the strongest characteristics of this model.

It provides substantial capacity for large AC motors and allows the drive to be applied to heavy industrial equipment where lower-current VFDs would be unsuitable.

12.2 High Normal-Duty Power Rating

The 400 kW Normal-Duty rating provides a substantial power envelope for conventional industrial applications.

This makes the model appropriate for many large pump, fan, blower, conveyor, and process-motor applications.

12.3 Heavy-Duty Capability

The 315 kW Heavy-Duty rating gives the drive a substantial capacity for more demanding applications.

Heavy-duty selection is particularly important when the machine experiences higher torque demand, repeated acceleration, or more severe operating conditions.

12.4 Integrated Industrial Networking

Embedded EtherNet/IP provides a straightforward route for connecting the drive with a broader automation system.

This can reduce the amount of traditional hardwired control required and can provide more detailed operating and diagnostic information to the control system.

12.5 Enhanced Local Operator Interface

The enhanced LCD full-numeric HIM provides convenient local access to the drive.

This is particularly useful during startup, commissioning, troubleshooting, and maintenance.

12.6 Robust Enclosure

The Type 12 / IP54 packaged construction provides a more protected installation format than an open-frame drive.

This can simplify integration into industrial electrical environments where dust, dirt, and general industrial exposure must be considered.

12.7 Filtered Configuration

The filtered configuration is useful for projects where electromagnetic compatibility is an important consideration.

Correct grounding, shielding, cable routing, motor-cable selection, and installation practices remain essential.

12.8 Large-Scale MCC Integration

The 800 mm deep MCC-style format is appropriate for large electrical installations.

Instead of treating the drive as a small standalone component, it can be incorporated into a structured industrial motor-control arrangement.

12.9 Local and Remote Control Flexibility

The combination of the local HIM and embedded EtherNet/IP gives the system both local and network-oriented operating possibilities.

This is useful for large plants where maintenance personnel need local access while operators and automation systems need centralized control.

13. Catalog Configuration Interpretation

20G1AJC770JN4NNNNN	400 VAC, 3 PH	770 A	450 kW	400 kW	355 kW	8	Enhanced LCD Full Numeric HIM

These models belong to the same general PowerFlex 755 high-power 400 VAC configuration family. The principal difference is output-current and corresponding motor-power capacity. 

For preliminary mechanical planning, these large Frame 8 configurations should be treated as occupying a broadly similar large-cabinet envelope, but the exact dimensions and weights must be confirmed from the applicable configuration drawing before installation.

15. Five Popular Allen-Bradley Models for Comparison

The following models are useful additional Allen-Bradley references when building a broader industrial-drive selection list.

Model	Series / Family	Input Class	Output Current	Typical Power Class	Frame / Construction	Protection / Configuration
20G1AGC260JN0NNNNN	PowerFlex 755	400 VAC, 3 PH	260 A	132 kW ND / 110 kW HD	Frame 7	IP54 / Type 12, air cooled

20G1AND302JA0NNNNN	PowerFlex 755	480 VAC, 3 PH	302 A	250 HP ND / 200 HP HD	Frame 7	Open-type IP20/IP00

These five models cover several different voltage classes and power ranges, making them useful when comparing PowerFlex 755 configurations across different plant electrical systems.

16. Comparison With the 650 A and 770 A Models

The most direct comparison for the 750 A version is with the neighboring 650 A and 770 A configurations.

Parameter	20G1AJC650JN4NNNNN	20G1AJC750JN4NNNNN	20G1AJC770JN4NNNNN
Input	400 VAC, 3 PH	400 VAC, 3 PH	400 VAC, 3 PH
Output Current	650 A	750 A	770 A
LD	400 kW	450 kW	450 kW
ND	355 kW	400 kW	400 kW
HD	315 kW	315 kW	355 kW
Frame	8	8	8
Cooling	Forced Air	Forced Air	Forced Air

Depth	800 mm class	800 mm class	800 mm class
HIM	Enhanced LCD Full Numeric	Enhanced LCD Full Numeric	Enhanced LCD Full Numeric
EtherNet/IP	Embedded	Embedded	Embedded

The 750 A configuration sits between the 650 A and 770 A models in current capacity.

For a motor requiring around 400 kW under normal-duty conditions, the 750 A model provides a strong fit within this group.

The 770 A model becomes more attractive when additional heavy-duty current capacity is required.

17. Comparison With the Previous Configuration

A particularly important comparison is the previous 20G1AJC750AN4NNNNN configuration.

The previous AN4 configuration was discontinued, with the 20G1AJC750JN4NNNNN identified as its direct replacement. 

Parameter	Previous Configuration	Current Configuration
Model	20G1AJC750AN4NNNNN	20G1AJC750JN4NNNNN
Series	PowerFlex 755	PowerFlex 755
Input	400 VAC, 3 PH	400 VAC, 3 PH
Output	750 A	750 A
ND Rating	400 kW	400 kW

Enclosure	Type 12 / IP54	Type 12 / IP54
HIM	Enhanced LCD Full Numeric	Enhanced LCD Full Numeric
Filter / CM Configuration	Previous configuration	Filtered / CM Jumper Installed
Status	Discontinued	Current replacement configuration

This comparison is important when replacing an older installation.

The catalog-number change should not be treated as merely a cosmetic revision. The replacement should be checked for electrical compatibility, control architecture, accessories, HIM requirements, wiring, configuration, and application-specific requirements before installation.

18. Installation Considerations

Because the 20G1AJC750JN4NNNNN is a large Frame 8 drive, installation planning is considerably more important than it would be for a small compact VFD.

The following areas should be considered.

Electrical Supply

The incoming supply should be compatible with the drive’s 400 VAC three-phase configuration.

Proper upstream protection and disconnect arrangements should be designed according to the applicable electrical standards and the requirements of the installation.

Motor Cable

The motor cable must be appropriately sized for the current, distance, installation environment, insulation requirements, grounding arrangement, and drive output characteristics.

Long motor cables may require additional engineering consideration because cable capacitance and high-frequency switching behavior can affect the motor-drive system.

Grounding

Correct protective grounding and high-frequency grounding practices are essential.

The drive, motor, enclosure, cable shielding, and associated control equipment should be integrated into a properly designed grounding system.

Cooling

The drive uses forced-air cooling.

Therefore, the installation must provide appropriate ventilation and clearance for heat dissipation.

The equipment room should be designed so that the heat generated by the drive does not cause the ambient temperature around the equipment to exceed the applicable operating limits.

Cabinet Clearance

Because the drive is an approximately 800 mm deep MCC-style Frame 8 configuration, the installation should allow sufficient front and rear access where required for maintenance, ventilation, cable termination, inspection, and service activities.

19. Maintenance Considerations

A large industrial drive should be incorporated into a preventive-maintenance program.

Typical maintenance activities can include:

• Visual inspection.
• Checking cooling-air paths.
• Inspecting fans.
• Checking cabinet cleanliness.
• Inspecting electrical connections.
• Checking grounding connections.
• Reviewing fault history.
• Reviewing operating temperature.
• Inspecting motor cables.
• Checking enclosure condition.
• Verifying operator-interface operation.
• Reviewing network communications.
• Checking for unusual vibration or acoustic changes.
• Inspecting signs of overheating.

For high-power installations, maintenance should be performed by qualified personnel using the applicable safety procedures and equipment-specific documentation.

20. Engineering Selection Guidelines

When selecting the 20G1AJC750JN4NNNNN for an application, the following parameters should be evaluated together rather than selecting solely according to motor horsepower.

Motor Rated Current

The motor’s actual rated current should be compared with the drive’s applicable current rating.

This is generally more meaningful than simply comparing motor kW values because motor efficiency, power factor, voltage, duty, and application conditions all affect current demand.

Motor Duty

Determine whether the application should be treated as light duty, normal duty, or heavy duty.

This directly affects the applicable power rating.

For this model:

• Light Duty: 450 kW.
• Normal Duty: 400 kW.
• Heavy Duty: 315 kW.

Acceleration Requirements

Heavy machinery may require substantial acceleration torque.

The application should therefore be evaluated for:

• Starting torque.
• Acceleration time.
• Load inertia.
• Motor inertia.
• Required current during acceleration.

Deceleration Requirements

If the motor must decelerate rapidly, the regenerated energy should be evaluated.

This is particularly important because this catalog configuration does not include dynamic braking.

Environmental Conditions

Ambient temperature, humidity, dust, altitude, enclosure conditions, and ventilation should all be evaluated.

The Type 12/IP54 packaged configuration provides a robust enclosure arrangement, but enclosure protection does not eliminate the need for proper environmental engineering.

21. Why This Model Is Attractive for Large Industrial Systems

The biggest advantage of the 20G1AJC750JN4NNNNN is the balance between very high motor-control capacity and integrated automation functionality.

A 750 A drive is capable of serving a large motor installation, while the PowerFlex 755 architecture provides the communication and diagnostic features expected in a modern industrial automation system.

The enhanced local operator interface is particularly useful for commissioning and maintenance.

The IP54 / Type 12 packaged construction is also advantageous when the drive must be integrated into an industrial electrical room or MCC-style installation.

The embedded EtherNet/IP capability can further simplify integration with centralized control systems.

22. Recommended Application Positioning

For engineering selection purposes, the 20G1AJC750JN4NNNNN can be positioned as a high-power, network-integrated, enclosed AC drive for large industrial motors.

It is particularly appropriate where the following requirements exist simultaneously:

• 400 VAC three-phase industrial power.
• Large motor capacity.
• Up to 750 A nominal output current.
• Up to 400 kW Normal-Duty application rating.
• Up to 315 kW Heavy-Duty application rating.
• Large MCC-style installation.
• IP54 / Type 12 enclosure requirements.
• Embedded EtherNet/IP communications.
• Local LCD operator interface.
• Filtered drive configuration.
• Industrial maintenance and diagnostic requirements.

23. Product Summary
